From: Frank Wunderlich <frank-w@xxxxxxxxxxxxxxx>
New Version (v1.0) of R2 pro has swapped gmacs compared to the v00.
WAN-Port is now on gmac1 (RTL8211F) and lan-ports on gmac0 with mt7531
switch.
There is already a mt7531 dsa driver in mainline, but it needs to be
modified to work for this board.
Fixes: f901aaadaa2a ("arm64: dts: rockchip: Add Bananapi R2 Pro")
